Stellar wind and atmospheric mass loss
Solar wind can erode the atmosphere of planets. Does anyone know or have pointers to how that would work out if you have a much smaller star with planets much closer. How can we compare atmospheric erosion on Earth to atmospheric erosion of a planet orbiting a much smaller (and dimmer) star but in the habitable zone of that star. For instance, let's say the star, uh, which star could I choose, oh, I got one let's say TRAPPIST-1. I know that the size of the planet and the composition of the atmosphere would be very important factors as far as atmospheric erosion goes. But I don't really want to consider those here. I would want to compare a similar sized planet, with a similar atmosphere and at a similar temperature. Just a smaller star. Alain Fournier |
